[Comparative studies of the physical properties of Metaplex and Duracryl].

Physical feature of Metaplex (Polish thermoplastic which could be used in stomatology) were studied, and were compared with a commonly used acrylic plastic Duracryl. The following studies were made: impact strength, bending resistance, bending resistance of adhesive-bonded joint of Metaplex with Duracryl, thermal resistance, and water absorptivity. Judging by the results Metaplex can be used in the oral cavity.
